<h1>Mesa 9.2.1 Release Notes / (October 4, 2013)</h1>

<p>
Mesa 9.2.1 is a bug fix release which fixes bugs found since the 9.2 release.
</p>
<p>
Mesa 9.2 implements the OpenGL 3.1 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 3.1.  OpenGL
3.1 is <strong>only</strong> available if requested at context creation
because GL_ARB_compatibility is not supported.
</p>
